13. To prevent damage to the O-rings, install the fuel injectors in the fuel rail first, then install them in the intake mani-

fold.

'95 - 96 models only:

14. Align the center line on the connector with the mark on the fuel rail ('95 - 96 models only).

15. Install and tighten the retainer nuts.

16. Connect the fuel hose to the fuel rail with new washers.

17. Connect the No. 7 vacuum hose and fuel return hose to the fuel pressure regulator.

18. Install the connectors on the fuel injectors.

19. Install the engine harness cover.

20. Turn the ignition switch ON (II), but do not operate the starter. After the fuel pump runs for approximately two seconds,

the fuel pressure in the fuel line rises. Repeat this two or three times, then check whether there is any fuel leakage.

PGM-FI Main Relay

Description

The PGM-FI main relay actually contains two individual

relays. This relay is located at the left side of the cowl.

One relay is energized whenever the ignition is on which

supplies the battery voltage to the ECM, power to the

fuel injectors, and power for the second relay. The second

relay is energized for two seconds when the ignition is

switched on, and when the engine is running, to supply

power to the fuel pump.

Relay Testing

NOTE: If the car starts and continues to run, the PGM-FI

main relay is OK.

1. Remove the PGM-FI main relay.

2.

Attach the battery positive terminal to the No. 2 ter-

minal and the battery negative terminal to the No. 1

terminal of the PGM-FI main relay. Then check for

continuity between the No. 5 terminal and No. 4 ter-

minal of the PGM-FI main relay.

If there is continuity, go on to step 3.

If there is no continuity, replace the PGM-FI main

relay and retest.

3. Attach the battery positive terminal to the No. 5 ter-

minal and the battery negative terminal to the No. 3

terminal of the PGM-FI main relay. Then check that

there is continuity between the No. 7 terminal and

No. 6 terminal of the PGM-FI main relay.

If there is continuity, go on to step 4.

If there is no continuity, replace the PGM-FI main

relay and retest.

4. Attach the battery positive terminal to the No. 6 ter-

minal and the battery negative terminal to the No. 1

terminal of the PGM-FI main relay. Then check that

there is continuity between the No. 5 terminal and

No. 4 terminal of the PGM-FI main relay.

If there is continuity, the PGM-FI main relay is OK.

If there is no continuity, replace the PGM-FI main

relay and retest.ProCarManuals.com

Troubleshooting Procedures

Checking the Diagnostic Trouble Code (DTC)

with an OBD II Scan tool or Honda PGM Tester

When the TCM senses an abnormality in the input or output systems, the indicator light in the gauge assembly will

blink. When the 16P Data Link Connector (DLC) (located behind the ashtray) is connected to the OBD II Scan Tool or Honda

PGM Tester as shown, the scan tool or tester will indicate the Diagnostic Trouble Code (DTC) when the ignition switch is

turned ON(II).

When the indicator light has been reported on, connect the OBD II Scan Tool conforming to SAE J1978 or Honda PGM

Tester to the DLC (16P) behind the ashtray. Turn the ignition switch on (II), and observe the DTC on the screen of the OBD II

Scan Tool or Honda PGM Tester. After determining the DTC, refer to the electrical system Symptom-to-Component Chart

on page 14-56 and 14-57.

NOTE: See the OBD II Scan Tool or Honda PGM Tester user's manual for specific instruction.

OBD II SCAN TOOL or

HONDA PGM TESTER

Some PGM-FI problems will also make the indicator light come on. After repairing the PGM-FI system, disconnect the

BACK UP RADIO fuse (10 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory, then

retest.

NOTE: Disconnecting the BACK UP RADIO fuse also cancels the radio anti-theft code, preset stations and the clock setting.

Get the customer's code number, and make note of the radio presets before removing the fuse so you can reset them.

9. Connect the A/T gear position switch connector,

then install the harness stay.

10. Turn the ignition switch ON (II). Move the shift lever

through all gears, and check the A/T gear position

switch synchronization with the A/T gear position

indicator.

11. If the A/T gear position switch does not synchronize

with the A/T gear position indicator, loosen the

bolts securing the A/T gear position switch and

adjust the A/T gear position switch installation.

12. Install the A/T gear position switch cover. Tighten

the bolt on the ATF pan side loosely so that there is

no clearance between the A/T gear position switch

cover and the ATF pan. Then tighten the bolt on the

rear cover side to the specified torque, and tighten

the bolt on the ATF pan side to the specified torque.

• The shift lever cannot be moved to the posi-

tion from the position without pushing the

• The back-up lights come on when the shift lever

is in the position.ProCarManuals.com

Pump motor control:

The ABS control unit monitors the brake fluid pressure in the accumulator by the pressure switch ON/OFF signals. The

ABS control unit turns the pump on when the pressure in the accumulator drops, and stops the pump when the pressure

rises to the specified value.

If the pressure does not reach the specified value after the motor has operated continuously for a specified period, the

ABS control unit stops the motor and activates the ABS indicator light.

Self-diagnosis function:

The self-diagnosis function, provided in the sub-function of the ABS control unit, monitors the main system functions by

constantly transmitting the data between the two Central Processing Units (CPUs). When an abnormality is detected, the

ABS control unit turns the ABS indicator light on and stops the ABS, although the basic brake system continues to operate

normally.

When the ABS control unit detects an abnormality with the ABS and turns the ABS indicator light on, the diagnostic trou-

ble code (DTC), which shows the problem part or unit, is recorded in the control unit. The DTC can be read by the blinking

frequency of the ABS indicator light.

Fail-safe function:

When an abnormality is detected in the ABS control sys-

tem self-diagnosis, the solenoid operations are suspend-

ed by turning off the two fail-safe relays. This discon-

nects the ground circuits of all the solenoid valves to

prevent ABS operation.

Under these conditions, the braking system functions

just as an ordinary one.

Fail-safe relay:

The fail-safe relay's terminal side contact is normally

open. When there is continuity at the relay coil, the fail-

safe relay is closed, thereby connecting the ground cir-

cuit to the solenoid valve.

ABS indicator light:
SOLENOID VALVE

BAT

REAR FAIL-SAFE RELAY

FRONT FAIL-SAFE RELAY

The ABS control unit turns the ABS indicator light on when one or more of the following abnormalities are detected. This

is only a partial list.

When the operating time of the motor in the power unit exceeds the specified period.

When vehicle running time exceeds 30 seconds without releasing the parking brake.

When absence of speed signals from any of the four wheel sensor is detected.

When the activation time of all solenoids exceeds a given time, or an open circuit is detected in the solenoid system.

When solenoid output is not detected in the simulated ABS operation when the engine is started or the vehicle is driven.

To check the indicator light bulb, the light is activated when the ignition switch is first turned on. The light goes off after

the engine is started if there is no abnormality in the system.
